(answer with "sometimes, always, or never true") A decimal number is an irrational number.

xxMikexx [17]

Answer:

Step-by-step explanation:

Sometimes. If the decimal never repeats itself and never ends, like pi, it is irrational. But if the decimal is .5 or .333333333333333... it either terminates (ends) or repeats itself forever, making it rational.

How to solve and respond.

son4ous [18]

Step-by-step explanation:

the error:

it is stated that

$\frac{5x}{x+7} +\frac{7}{x} = \frac{5x}{x+7} +\frac{7(7)}{x+7}$

subtract (5x)/(x+7) from both sides

$\frac{7}{x} = \frac{7(7)}{x+7}$

multiply both sides by x + 7

7(x+7) = 49x

7x + 49 = 49x

subtract 7x from both sides to isolate x and its coefficient

49 = 42x

thus, this is only true when 49 = 42x. in order for these two equations to be equal, they must always be true, so this is wrong

the solution:

we want to express 7/x as (something) / (x+7). to do this, we can multiply 7/x by 1.

anything divided by itself = 1. thus, if we multiply both the numerator and the denominator by something that turns x into (x+7), we can do what we want to do.

(x+7)/x * x turns x into (x+7), so we multiply both the numerator and denominator by (x+7)/x to get

$\frac{7}{x} = \frac{7(x+7)/x}{x+7}$
